The continue statement
The continue statement is used inside a loop when there is a requirement to jump to the next iteration of the loop immediately. The continue statements can be used only within some loop(for-loop, while and do-while, etc) and transfers control to the end of the loop's body. In the case of a while and do-while loops, this causes the loop expression to be evaluated next. In the for-loop, this causes the increment/decrement(update) to be evaluated before the loop expression.

The example continue-statement
public class Demo {
public static void main(String[] args) {
int arr[][]= {{0,1,0,0},
{0,0,0,0},
{0,1,1,0},
{0,0,0,1}};
for(int i=0;i<4;i++)
{
for(int j=0;j<4;j++)
{
if(arr[i][j]==1)
{
continue;//statements after continue will not
be
} //executed if condition is fulfilled
System.out.print(arr[i][j]+"\t");
}
System.out.println();
}
}
}
Output:
0 0 00 0 0 0
0 0
0 0 0
The labeled continue statements
We can also use labeled continue, labels are used to uniquely identify the loops if they are nested inside each other. like
continue label_name;
The continue statements are generally used inside if statement,

The example labeled continue-statement
public class Demo {
public static void main(String[] args) {
label_outer:
for (int i = 1; i < 6; ++i) {
for (int j = 1; j < 5; ++j) {
if (i == 3 || j == 2)
continue label_outer;
System.out.println("i = " + i + "; j = " + j);
}
}
}
}
Output:
i = 1; j = 1
i = 2; j = 1
i = 4; j = 1
i = 5; j = 1
